[RE-wrenches] HIQ Inverter Experience?

[jay]

Hi Patrick

I would add that the NEMA 6 rating is for dust/water intrusion, not corrosion resistance.  

I don’t know what the metallurgy of the Enphase was/is or the HIQ.
But I would not make the assumption that whats bad/good for one is the same for any other.

We submitted some pictures to Solar Pro for an article they are writing. HIQ are NEMA 6.  I have no experience with them, and was wondering if anyone did.  Thank you, Chris
